CAR-COUPHNG.

SPECIFICATION forming part of Letters Patent No. 781,949, dated February'7, 1905.

Application filed May 5. 1903. Serial No. 155,765.

To all whom, it may concern:

Be it known that I, ELI H. JANNEY, a citizen of the United States,residing in Fairfax county, State of Virginia, have invented new anduseful Improvem'entsin (Jar-Couplings, of 1 which the following is aspecification.

My invention relates to car-couplings, and more particularly to thatclass known as the Janney type, and has for its objects, first, toprovide improved means for automatically rotating the coupling-hook toits open position by means of a vertically-movable locking-pin, and,secondly, to provide improved means for setting the locking-pin in theunlocking position and for automatically disengaging it from said setposition by the movement of the tail of the coupling-hook. These objectsI accomplish in the manner and by the means hereinafter described andclaimed, reference being had to the accompanying drawings, in

Y which:

Figure 1 is a proved coupling, showing the same in its open position.Fig. 2 is a detail perspective view of the coupling-hook detached. Fig.3 isa detail perspective view of the locking-pin. Fig. & is a bottomplan view of the coupling. Fig. 5 is a vertical longitudinalsectionalview, the couplinghook and lockingpin being shown in full lines. Fig. 6is a similar view,

the locking-pin being shown raised and retained in the unlockedposition. Fig. 7 is a vertical transverse sectional view takenimmediately in front of the locking-pin. Fig. 8 is a horizontalsectional view showing the coupling in the lock-set position. Fig. 9 isa detail sectional view similar to Fig. 7, showing the tail of thecoupling in the act of movingto the locked position, the locking-pinbeing shown partly raised thereby. Fig. 10is a View similar to Fig. 6,illustrating a slightlymodified construction.

Similar numerals of reference denote corresponding parts in the severalviews.

In. the said drawings the reference-numeral 1 denotes the draw-bar ofthe coupling, carrying the draw-head 2 of the well-known J anney type,in'which is pivoted, by means of pin 3, the usual coupling-hook 4.Passing vertically through the upper and lower apertures l 4 l l lperspective view of my imslightly beyond the side face of the pin, as

shown in Figs. 3 and 7. The tail of the coupling-hook t is reversclyinclined on its upper and lower surfaces at 11 and 12 to correspond withthe inclines 9 and 10. said upper incline l1 merging into a flat surface13, having a rounded projection 14 centrally thereon, said projectionhaving a flat top surface and adapted to engage a narrow flat surface 15at the lower end of incline 9 in a manner hereinafter to be described.

Below the recess 8 in the pin 7 is another reccss 16, having its upperedge 17 inclined upwardly and inwardly to engageashoulder 18, formed onthe inner fron face of the lower aperture 6 in the draw-head when saidpin is raised to the unlocked position, the latter having its upper edgebeveled to correspond with that of the upper edge 17 of recess l6,-asshown in Fig. 6. It will also be observed that the lower edge 20 ofrecess 16 is inclined downwardly and that the front side of thelocking-pin 7 below said recess projects somewhat bcyond the verticalsurface of said pin above said recess also for a purpose hereinafter tobe described. i

Formed in the side of pin 7 and just below the lower edge of thedraw-head when said pin is in its lowermost position is an incline l9,adapted to perform the following double function: 'hen the pin 7 is inits lowermost position and the coupling-hook at locked thereby, thetraction on said coupling-hook will force the lockingpin 7 to the right,as shown in Fig. 7, thus causing incline 19 to underlie the lower edgeof the draw-head 2 and effectually preventing any upward creeping of thelocking-pin 7, due to the jolting of the cars while in motion, wherebythe locking-pin 7 might otherwise ultimately be lifted suflicicntly torelease the coupling-hook 4. The other function of said incline 19 isperformed when the locking-pin 7 is lifted to automaticlocatedally throwthe coupling-hook 4: to its open poling-hook tail. By referring to Fig.6 it will be observed that the lower incline 12 on the tail of thecoupling-hook 4 is also inclined up: wardly and forwardly and that thecoacting lower incline on the locking-pin 7 is correspondingly inclinedfor a purpose hereinaf:

' ter to be described.

. From the above description the operation of my improved constructionwill be understood to be as follows: With the pin 7 in its lowermostposition and the coupling-hook t open, as shown in Fig. 1, the device isready for automatic coupling, the rotation of said hook causingcam-surface 11 on the tail thereof to contact with cam 9 on the pin 7,and thus raise the latter until the coupling-hook tail passes the same,when it will drop automatically, and thus lock the hook in its closedposition. Now when it is desired to uncouple the pin 7 is lifted, bymeans of its cord or chain, until the-incline 10 on the pin engagesincline12 on the hook, when by reason of the forward and upward inclineof the same 'as shown in. Fig. 6, the lower end of the pin will bepositively tilted forward, thus bringing the recess 16in said pin inengagement with shoulder 18 in the draw-head when said pin reaches theunlocking position, and thus retaining said pin in this position, sothatthe coupling-hook 1 may be turned -t-o its open position, thuspermitting the cars to separate. By referring to Fig. 8 it will beobserved that the locking-pin 7 has its edge or corner nearest the tailof the coupling-hook L beveled at 2l,and this forward movement of thelower end of saidlocking-pin brings it into the path of movement of thetaii of the coupling-hook 4, so that the latter in its movement to theopen or closed position will contact with the beveled edge 21 thereofand automatically force said locking-pinbackward again to disengagerecess 16 from shoulder 18, thus permitting said locking-pin to drop toits locking position when said coupling-hook has rotated away fromengagement therewith. It may happen sometimes, however, that owing to avariation in the castings the tail of the coupling-hook 1 will not belong enough to thus contact with the locking-pin 7, and as it isessential that the latter shall be disengaged from the shoulder V 18 anddrop to its locking position when the coupling-hook 4 is swung to theclosed position I have provided the following means for insuring thisresult: The locking-pin 7 when in engagement with'the shoulder 18 hasthe lower edge of its incline 9 slightly below the upper edge of therounded projection 14 on the tail of coupling-hook 4, and the latter inits movement to the open position will contact with its projection- 1awith the flat surface 15 on the locking-pin 7, thus slightly lifting thelatter to disengage it'frorn the shoulder 18. By referring to Fig. 6 itwill'be'seen that' the fiat surface. 15 on the locking-pin is alsoinclined upwardly and out wardly, so that this contact will take placeonly at a point near the inner end of said flat surface or. at thecenter of gravity of said locking-pin,- thus causing said'locking-pin toresume its vertical position when lifted from engagement with theshoulder 18, and per- 18 when released by the coupling-hook tail. itwill be further obse. ted that as the flat surface 15 'on the lockingpin, passes out. of contact with the projection 14; n the coup-:ling-hook tail during the movement of the latter to either the lockingor the unlocking position it will first drop onto the fiat surface 13 onthe coupling-hook tail, and said ,pin will thus be maintainedmomentarily in the vertical position and will at the same time havedropped sufiicie'ntly to bring the upper edge 17 of its recess 16 belowthe shoulder- 18 on the draw-head, so that engagement of the two will beimpossible. fore, that with the pin 7 in the lock-set position amovement in either direction of the tail of the coupling-hook beneaththe surface 15 on the pin 7-will result in the latter being It follows,there I nittin'g it to drop free from said projection lifted anddisengaged from the shoulder 18, a

so that it will drop to the locking position. It will readily be seenthat, if desired, the

projection 18 may be located in the rear face of the lower aperture 6 ofthe draw-head and the recess 16 correspondingly located in the rear faceof the locking-pin 7. for by reversing the forward and upward incline ofincline l2 and similarly reversing that of incline 10 the result will bethat when said inclines contact as the locking-pin 7 is lifted the lowerend of the latter will be positively forced backward instead of forward,thus insuring the engagement of recess 16 with projection 18, as shownin Fig. 10. With this construction the flat surface 15 of the lockingpinwili'be inclined upwardly and inwardly instead of upwardly andoutwardly, the result being that as the coupling-hook tail passesbeneath said flat surface 15 the consequent slight lifting of thelocking-pin 7 will result in the lower end of the latter being tiltedforward away from engagement with the projection 18, and thus causingthe locking-pin to fall to itslowerniost position.

It will be observed that the inclining or beveling of the engaging face17 of recess 16 and the shoulder 18 will insure their engagement betterthan if said faces were flat, and

'willeifectually prevent their accidental disengagement.

In order to positively rotate'the couplingh ok-4 to itsopen position bymeans of the 3 locking-pin 7,1.have provided the inclines 10 and 12,operating as follows: \Vh n the coupling-hook is locked, but not engagedwith another coupling-hook, the lifting of lockingpin 7 will cause theprojecting upper end of incline 10 thereon to engage the incline 12 onthe tail of said coupling-hook,and the fur: ther lifting of saidlocking-pin necessarily rotates said coupling-hook to its open positionin a manner readily understood: .In order that this engagementof saidinclines may be insured, l have provided the incline 19 on the oppositeside of the locking-pin 7, which by its contact with the lower edge ofthedrawhead as the locking-pin is raised forces saidlocking-pin towardthe tail of the couplinghook, as seen in Fig. 7. So, also, in order thatwhile the pin 7 is being lifted to throw the coupling-hook open thevertical face of the recess 8 therein may be out of the path of travelof the coupling-hook tail during its rotation to the open position, sothat any binding of the parts may be prevented, 1 have provided theinclined lower face 20 for the recess 16 and have projected the frontface of the locking-pin 7 below said recess, the result being that assaid pin is lifted said face 20, contacting wi the lower end of pincarry said pin out of the path of travel of the tail of thecoupling-hook. Furthermore, this positive backward movement of the lowerend of the pin 7 will permit said ,pin when released to drop freely toitslowermost position without danger of its engaging projection 18.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a car-coupling, the combination with the draw-head, of acoupling-hook pivoted therein and having inclines in reverse directionson the upper and under sides of its tail, and a vertically-movablelocking-pin for said coupling-hook on the tail of ti poses set forth.
